Description

Technical Field

[0001] The utility model relates to the technical field of air compressor equipment, in particular to a shock absorbing support device for an air compressor. Background Art

[0002] An air compressor, also known as an air compressor, is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type and are widely used in industrial production. When an air compressor is working, it will vibrate. The air compressor itself is affected by the vibration and is easily damaged.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN216743463U discloses a shock-absorbing support device for an air compressor, including a U-shaped fixed block, a fixed rod is fixedly arranged on the left and right sides of the bottom of the inner cavity of the U-shaped fixed block, and two groups of the fixed rods are movably arranged with connecting rods on the left and right sides through movable blocks, and four groups of connecting rods are movably arranged with moving blocks on the top through movable blocks, and the two groups of connecting rods are movably arranged through a first spring. The air compressor support device is provided with a fixed rod, a first spring, a connecting rod, a moving block, a first sliding block, and a first slide groove. During the use of the air compressor support device, the fixed rod, the first spring, the connecting rod, the moving block, the first sliding block, and the first slide groove are provided, which effectively ensures that when the support rod is subjected to force again, the connecting rod opens to drive the moving block to connect the first sliding block to slide in the first slide groove, and the first spring has a buffering and shock-absorbing effect, which reduces the vibration of the device, thereby improving the service life of the air compressor; however, this shock-absorbing support device has the following defects:

[0004] It can only provide shock-absorbing effect for vibrations generated in the vertical direction, while the air compressor not only generates vibrations in the vertical direction, but also in the horizontal direction, so the shock-absorbing effect is poor; it uses spring buffering for shock absorption, but there is no good damping structure. After being vibrated, the spring compression stroke is large and the rebound stroke is also large, which may cause the air compressor to shake more.

[0005] For this reason, we propose a shock-absorbing support device for an air compressor to solve the above problems. Utility Model Content
